Zusammenfassung:The housing (2) has a base (3) which forms an axial catch for a bearing receptacle (4) with a bearing shield (7), where the housing is manufactured by forward impact extrusion process, backward forward impact extrusion process or forward and backward impact extrusion process using aluminum forging alloy. The housing receives an armature shaft (10) and a stator (12), where the armature shaft is rotatably supported in bearings (15, 16). The housing forms a heat sink for an electrical machine (1). An independent claim is also included for an electrical machine comprising bearings. Die Erfindung betrifft ein Gehäuse einer elektrischen Maschine, die mittels eines Fließpressverfahrens hergestellt ist. Die Erfindung betrifft ferner eine elektrische Maschine, mit einem solchen Gehäuse zur Aufnahme einer in Lagern drehbar gelagerten Ankerwelle und eines Stators, wobei das Gehäuse mittels eines Fließpressverfahrens hergestellt ist.
